However, the new radiometric calibrations for these settings were not in place in time for this PDS release. Thus, the RDR files from 2017074 to 2017165 are not optimally calibrated radiometrically. We plan to release updated versions (version 04) of these RDR files in a future delivery that will incorporate a better radiometric calibration. At 04:19:32 UTC on October 5, 2016 (DOY 279), the LAMP failsafe door was opened. This increased the total size of the instrument's light-admitting aperture by about 10% of the size of the airglow aperture. FITS files containing data taken after this LAMP configuration change are identified by the keyword "FAILSAFE" (with value = "T") in their primary headers. The instrument effective area used to produce the calibrated LAMP data has been adjusted by this factor in the pipeline code. A better such calibration for data taken after the failsafe door opening will be included in the future version 04 RDR files. New File Additions ================== In this thirty-first data release, there are 1286 new RDR files supplied. Modifications to Existing Files =============================== None.
